Abstract: The present invention is directed to processes for preparing stable 1-amino-1- cyclopropanecarboxylic acid (“ACC”) water-soluble granules comprising the steps of mixing a composition comprising ACC and water at a concentration ratio at about 2.0:1 or less to create a wet mass, extruding the wet mass to create an extrudate and drying the extrudate to create the water-soluble ACC granules, wherein the concentration of ACC and water is weight by total weight of the wet mass. The present invention is further directed to ACC granules produced by processes of the present invention.

Abstract: Nanoengineered particulate coatings (NPCs) comprise a multiplicity of particulate hosts that are infused with a nanophase comprising a surfactant and at least one guest. The particulate hosts can be clay particles, the surfactant can be a cationic surfactant, and the guest can be an insect repellant. For example, montmorillonite particles infused with hexadecyl trimethyl ammonium bromide and garlic oil form NPCs that may be used to form an emulsion or suspension for spraying on citrus trees to repel Asian Citrus Psyllid.

Abstract: A continuous reaction system (CRS) allows a method to prepare quantum dots (QDs) in a continuous manner with high precision. The CRS pumps a plurality of reagent fluids into one or more mixing sites to form a reaction fluid that is carried through a heating chamber at elevated pressures to carry out hydrothermal growth of the QDs. The pumps and heating chamber are controlled with a high precision by employing a detector downstream of the heating chamber to provide a signal that is dependent on the composition and size of the QDs. The signal is provided to a signal processor that provides a signal that control the flow rates and temperature parameters in the system. The QDs produced in this manner are consistent in size and composition and can be of a single semiconductor composition or can be core-shell QDs with a shell semiconductor formed on a core semiconductor.

Abstract: Colored clay particles are prepared by the absorption of pigments, such as dyes, on the surface of clays. The surface of the clay can be modified with a surfactant such that a dye can be well bound to the particle's surface to avoid leaching of the dye into water. The colored clay particles can be used to deter insects, such as the Asian Citrus Psyllid (ACP), by coating a plant, such as a citrus plant, with the colored clay particles. The reflectance of the visible and ultraviolet light can be altered by the choice of dyes such that the spectrum visible to the insect deters the insect from the plant.
